Abstract
The utility model relates to a mechanical pressure sensor for controlling pressure, particularly to a plane pressing seal type mechanical pressure sensor. The sensor consists of an adjusting sleeve, an adjusting seat, a switch lever, a tension spring and a micro switch. The adjusting sleeve and the adjusting seat are fixedly connected together by a check nut and an O-shaped seal ring. The micro switch is arranged on the side surface of the adjusting seat by a micro switch cover. A switch cap is arranged below the adjusting seat, a spring top cap is arranged on the bottom of the adjusting sleeve by a stopper screw, and an adjusting spring is arranged between the switch cap and the spring top cap. An adjusting seat insert is arranged in the adjusting seat, and the switch lever is arranged in the adjusting seat insert. The utility model is characterized in that a step groove is arranged on the top end of the adjusting seat insert, a seal strip is arranged in the step groove, the seal strip is pressed on the end part of the seal strip, a lock sleeve is arranged on the inner wall of the step groove, and the lock sleeve is pressed on the seal strip. The utility model can ensure persistent seal effect and resist corrosion and high temperature. The service life is long.
Description
Technical field
The utility model is a kind of mechanical compression sensor of controlled pressure, and particularly a kind of plane that is used for high pressure painting machinery or spray gun compresses sealing machine formula pressure transducer.
Background technology
Prior mechanical pressure transducer, its structure as shown in Figure 1, it is made up of regulating sleeve 1, adjustment seat 2, switch lever 3, tension spring 4 and microswitch 5; Regulating sleeve 1 and adjustment seat 2 are by also cap 6 and O RunddichtringO 7 are fixed in one; Microswitch 5 is located at the side of adjustment seat 2 by microswitch lid 8, be provided with deflating cap 9 below the adjustment seat 2, the bottom of regulating sleeve 1 is provided with spring top cap 11 by holding screw, holding screw 10 is mainly used in pressure regulation, be provided with tension spring 4 between deflating cap 9 and the spring top cap 11, be provided with adjustment seat inserts 13 in the adjustment seat 2, switch lever 3 is plugged in the adjustment seat inserts 13 and from its top and stretches out, and is provided with tension force O-ring seal 12 between switch lever 3 and the adjustment seat inserts 13.The defective of this structure is that sealing reliability easily produces bigger difference with the quality of tension force O-ring seal, when the fatigue strength of inner tensions spring is not enough, also can influence sealing effectiveness.
Summary of the invention
The purpose of this utility model is for the sealing reliability that overcomes existing machinery formula pressure transducer easily produces defective than big-difference with the quality of tension force O-ring seal, invents the plane that a kind of end at switch lever is provided with diaphragm seal and compresses sealing machine formula pressure transducer.
The purpose of this utility model realizes as follows: described plane compresses sealing machine formula pressure transducer, is made up of regulating sleeve, adjustment seat, switch lever, tension spring and microswitch; Regulating sleeve and adjustment seat are by also cap and O RunddichtringO are fixed in one; Microswitch is covered on the side of adjustment seat by microswitch, be provided with deflating cap below the adjustment seat, the bottom of regulating sleeve is provided with spring top cap by holding screw, be provided with pressure spring between deflating cap and the spring top cap, be provided with the adjustment seat inserts in the adjustment seat, switch lever is plugged in the adjustment seat inserts, it is characterized in that: the top of adjustment seat inserts is provided with a stepped recesses, be provided with diaphragm seal in the stepped recesses, diaphragm seal is pressed in the end of switch lever, the inwall of stepped recesses is provided with lock sleeve, lock sleeve be pressed in diaphragm seal above.
The end of described switch lever is spherical.
Described diaphragm seal adopts the PE material, and lock sleeve adopts stainless steel to make.
Good effect of the present utility model is as follows: as long as guarantee between diaphragm seal periphery and the lock sleeve enough snap-in forces are arranged, just can guarantee lasting sealing effectiveness; Because diaphragm seal adopts PE material seal cover to adopt stainless steel, has guaranteed that diaphragm seal and sealing shroud are corrosion-resistant, high temperature resistant, the life-span is long.
